CULTIVATOB GANG CONNECTION. f

To all whom it may concern Be lt'known that I, SPENCER HERMANUS PHELPS,a, citizen of the United States of America, residing at Evansville, inthe county of Vanderburg, in the State of Indiana, have invented certainnew and useful Improvements in Cultivator Gang Connections, whereof thefollowing is'a specification.

This invention relates to cultivator couplingswhich connect theplowbeams of gang plows with the axle or frame and allow lat eral andvertical swing of the plows when in use. Such couplings usually havemeans for lateral adjustment on the axle to regulate the distancebetween theplows or gangsof plows and means for vertical adjustment ofthe beam .connection't'o adapt the'plows'to take a deeper or shallowercut.

' The invention relates more specifically-to improved means foreffecting vertical locked.

adjustments of the coupling members at different'heights whilemaintaining a continuous operative connection of said members during theadjusting operation.

The invention also relates to the peculiar coupling whereby it issimplified. v

Fig. 2 represents a plan view thereof.- Fig. 3 representsaside elevation of the worm adjuster thereof whereby theplowbeams may bereadily raised and lowered and retained in their Fig. at represents de-'adjusted position. tached parts of thegangcouplingconstituting a part ofthisgang connection.

, Paaad S p .1914- the cultivator of Fig. 7. Fig. 9 represents a plan ofthis gang connection adjusted in the loop of sa1d cranked axle. Fig. 10represents a transverse section of the axle coupli'ngof this embodimenton line 1O 10 of Fig. 7, looking in the direction indicated by thearrow. a

The same reference'numbers indicate corresponding :parts throughout thedifferent figures, round numbers being used for the principal elementsand intermediate numbers for the subordinate features thereof. Intheform of embodiment of this inventionillustratedin Figs. 1 told thisgang connection-comprises a gang coupling 10 attachable to the'plowbeams A' and B 'of a gang of plows of a o'ultivator, an axlecoupling 20 horizontally adjustable on a sleeve 30 loose on the axle C"of the cultivator, and

a vertically movable worm shaft Ojour nalecl in said gang coupling 10,adjustable vertically by itshown rotation in said axle coupling andoperative to raise orv lower said plowbeams in unison with its own riseand-1:

fall.

-The gang coupling'lO comprisesa horizontal rearwardly extendingattaching plate 11 and a forked bracket 12 integral therewith. Theplowbeams A and B are secured.

to opposite faces of said plate 11,- preferably between parallel ribsthereof by means of bolts in the usual manner. The upper horizontal arm13 of said forked bracket is preferably integral with. the body thereofandis provided with a-journalwbearing. 1-l.- The lower arm 15 of saidforked bracket is detachable from the body thereof and provided with aournalbearing 16 in alinement with the bearing 14; 'Thisdetachable arm15 is also provided with a bolthole 17 and at its rear end with a lip 18which engages the rear face of the body of the bracket 12 .as shown inFig.1. The lower end of the body of thebracket 12 is provided with a T1;

shaped slot 19 adapted to receivethe head andshank of a bolt 19"'whichpasses through hasra spiral screw-thread ,along its body,

journalstland 12 at its opposite ends adaptx The vertically ad ustablewormnshaft 40" ed toturn in the bearings l l'and 16 of the gang coupling10 and a rotation means preferably in the form of a projection 4:8 andadapted to be engaged by a wrench for turn ing the worm shaft in,v itsbearings.

The sleeve 30 fits loosely on the axle C and is adapted to turn thereon.This sleeve is preferably constructed in sections.

The axle coupling 20 comprises a vertical sleeve or tubular clamp 21having an interior screwthread adapted to fit the worm shaft 40, ahorizontal tubular clamp 25 adapted to fit the sleeve 30 and a web 22integrally connecting said clamps. The clamp 21 is in the form of asplit sleeve and is provided with a screwthread which corresponds withthe screwthread of said worm shaft. This split sleeve 21 is provided atits split edges with ears 23 and 2 1 having bolt holes for receiving aclamping bolt 26. for tightening the clamp around the worm shaft. Thejaws of the horizontal clamp 25="are provided with bolt holes forreceiving clamping bolts 27 and 28 and for holding the axle clamp inadjusted position on the horizontal sleeve 30. The upper lip of thehorizontal clamp 25 is provided with a lug 29 to receive a brace orsupporting rod D leading to the whiflletree support E connected with thedraft bar F.

In Figs. 1 to 6 this gang connection is illustrated as applied to anordinary arched axle C and in Figs. 7 to 10 it is shown inconnectionivith abalanced axle G in which the wheels are supported onrearwardly ex-v tended crank bends G.

In the embodiment shown in Figs. 7 to 10, the sectional axle sleeve 50corresponding to the axle sleeve 30 of the other form is made insections which are connected on one slde by means of a hinge 51 and onthe other side by means of perforated lugs 52 through which a clampingbolt 53 is passed.

In this case the sleeve 50 is provided with a spline 54: and the axleclamp with a groove engaged by said spline. This sleeve 50 is placed onthe axle Gr between the cranked end G and the upright G of the arch andis held in place endwise by these bends of the axle.

In the use of this invention the plowbeams may be adjusted higher orlower and locked in adjusted position without the use of a multiplicityof parts and without disengagement of the coupling members. hen it isdesired to adjust the plowbeams higher or lower, the locking bolt 26 ofthe clamping sleeve 21 is loosened sufliciently to permit the screwshaft410 to turn in said sleeve. Then a wrench is placed in engagement withthe angular pro ection or rotation means 43 at the upper end of saidscrewshaft and said shaft is turned toward the left for lowering theplowbeams or toward the right for raising them. This turning of thescrewshaft raises or lowers said shaft bodily While the clamping sleeve21 remains stationary. The forward ends of the plowbeams move up or downin unison with the raising and lowering of said screwshaft. WVhen thescrewshaft is at the upper height in the sleeve to secure a desiredadjustment of the plowbeams, the locking bolt 26 is operated to tightenthe clamping sleeve on said screwshaft, whereby any accidental turningthereof is prevented during the lateral swing of the plowbeams.

The coupling thus constructed is simple in construction, composed of fewparts, easily operated to effect vertical locked adjustments of theplowbeams and maintains the parts of the coupling in continuousoperative connection during the adjusting operation. i a I claim as myinvention: I 1.
